1) change of mindset
2) change of environment
I would say mindset should be considered here as a means that aids s successful business, everything starts with your mind just as your custodian of your thoughts the inner workings of your mind plays a key role here and if it's grounded on negativity there's no way that business will thrive but if it's grounded on positivity then you're gradually on the line of success.
It is not wrong with what you said, because every job and plan for all that work must be based on a positive enough mind because that is what will drive the action from ourselves to start it. So that the wise path will be formed when the path of our mind is on the right track, because great success will not happen through negative thoughts and it is really not suitable if used in any business. So the right mindset must come first before making plans and also making decisions in doing business for the long term.
